Key Features of Microcontroller Based Sinewave Inverter/UPS

• Single chip embedded INVERTER engine based universal card capable of voltages from 12V to 48VDC & power from 500VA to 3KVA
• 110V to 295V mains voltage window or computer compatible voltage window180V to 270V close loop regulated inverter output.
• Relay changeover near zero current/zero voltage. & Synchronized change over
• Over current of MOSFETs protected within micro seconds with processor reset.
• Power failure checking by simultaneous several methods.- when computer compatible
• Can accept any input waves like sine wave, generator waves etc. if voltage & frequency is within limit.
• Near to RMS measurements for all calculations.
• MOSFETs drain spikes protected.
• In built PFC controlled charger using same mosfets with charging current selectable from 100mamps to 20 amps. Electricity saving compared TRIAC, SCR and capacitor charging. Full charge cut selection mode for Tubular and Automotive batteries.
